Bitcoin has been steadily dropping for most of 2018, amd the stock crash was just reported very recently.
And there is a very credible explanation for the recent large dip in the bitcoin market, and this was due to loss in miners.
The stock crash could have an effect, but it's not the principal factors and there is no basis to claim BTC may not rise again.
The main issue in this regard with the crypto market is that the only channel to investing is through FIAT such as USD.
I read about a football club, which opted to pay its employees using cryptocurrency, if this could be adopted by more organizations. It would boost adoption and would also separate the stock and cryptocurrency market.
